In one example in accordance with the present disclosure, a computing device is described. The computing device includes a number of ports. Each port receives a connection to a display device. A first port is coupled to the first graphics processor which supports a number of display devices and a second graphics processor. The computing device also includes a controller. The controller determines when a number of coupled display devices is greater than the number of display devices supported by the first graphics processor and switches the first port from being driven by the first graphics processor to be driven by the second graphics processor.
